Filed: 1987-01-27
Abstract: PURPOSE:To accurately control an induction motor against a variation in a secondary resistance due to temperature, etc. by vector-controlling it by always correcting the resistance. CONSTITUTION:A primary current is supplied by a current comparison type PWM inverter 2 to an induction motor 1, and its rotating speed is detected by a resolver 3 and a speed detector 4. A controller A compares the detected speed value with a set speed value, a speed control amplifier 5 proportionally integrates it to output a torque current command value. An exciting current command value is given as a fixed value, and a slip angle frequency calculator 6 obtains a slip angle frequency from both the command values and a secondary time constant. An inverter frequency is obtained by the addition of the slip angle frequency and the detected speed value, and sine and cosine signals are obtained by a trigonometric function generator 7 from the inverter frequency. Multipliers 8, 9 amplitude-regulate the sine and cosine waves with a current command value as an amplitude control signal, and output 3-phase current command values.

Abstract: PROBLEM TO BE SOLVED: To enable simple switching of the number of openings of an optical system and to realize ultrahigh resolution by constituting the space modulation element of a part functioning as a diffraction type lens element and a part functioning as a rotary polarization optical element, and controlling functions of the diffraction type lens element and the rotary polarization optical element by an electrical signal. SOLUTION: When the function of a diffraction type lens element 105 is stopped and the function of the rotary polarization optical system 106 is made valid, since linearly polarized light passing through the optical rotating optical element 106 and linear polarization light passing through the diffraction type lens element 105 intersect orthogonally to each other, ultrahigh resolution is produced. The number of openings for an optical device is decided by a condenser lens 107, read and write of DVD are performed in this state. Next, when a function of the optical rotating optical element 106 is stopped and a function of the diffraction type lens element 105 is made valid, ultrahigh resolution will not be produced.  The focal distance of an optical device is made a combined focal distance by the diffraction type optical element 106 and the condenser lens 107, it is assumed that the number of openings is varied as compared with that of the condenser lens 107 only, and reading of a CD is performed in this state.

Title: Heat resistant bridge-formed wire
Inventor: SHIYUKUJIMA SATOSHI
IPC: H01B3/30
Filed: 1989-01-27
Abstract: PURPOSE:To obtain a low-cost heat resistant bridge-formed wires by having thermoplastic resin with aromatization or heterocycles in molecules made into an insulating layer and bridged by radiating ion beams with great energy. CONSTITUTION:It is impossible to bridge polymer with aromatization or heterocycles in molecules if electronic beams are radiated, however it is possible if ion beams are radiated. The reason why it can be bridged by radiating the ion beams is that the radiation of the ion beams is much greater (few thousands times) in energy given to per unit volume than that of the electronic beams and that the opening of benzene rings and heterocyclic rings, not caused by the electronic beams, is caused by the ion beams. It is suitable that the energy of the ion beams is within 0.1MeV and 50MeV, and the radiated amount of the ion beams is 1X10<11>/cm<2> to 1X10<15>/cm<2>. Thus, a relatively low cost resin is used to obtain the heat resistant bridge-formed wires excellent in thermal transformation property.

These decoded values are sent to the circuit 22 for correction of the output value of the circuit 22.
